Microwave Missing from my order

I have been calling the customer care line and the call centre for about three weeks now to make follow ups on my missing microwave, I have received no help whatsoever, no feedback or even a call to tell me whats going on. One of your consultants ( Sipho) who answered my call 2 weeks back Thursday, 19-11-2015, promised that the microwave will reach me within 3 working day. I called again (24-11-2015)and Steve promised to call me before 2pm yesterday, to give me the waybill number. No one has contacted me and I have already called about 5 times. On Saturday I went to the Boardmans store in Centurion Mall to seek assistance. The floor manager called Boardmans online, Donald answered the phone and promised to call me back within an hour as he needed to check my details on the system. Well Wednesday the 2nd of December today and I am still waiting for Donald's call. I am currently holding the line as I type this message, Itumeleng is apparently checking my order on the system and she comes back say the issue has been escalated. That's what everyone has been saying to me. The average time i spend on all these calls is 20min and guess who mhas to foot the the BILL!!!
